Axles and re-drilled rear drums for 4.5 bolt pattern

They're not welded, and 2'' grade 8 bolts so that's an upside.

Your in luck. Take them out and have them cut to the original stud head thickness and spot weld them after reinstall.

Cutting them is to clear the park brake strut if you using your park brake. Spot welding them is to prevent them from turning in when installing lugs.

Have fun
